STANISLAUS PIWONSKI, OF NEWARK, NEW J ER-SEY,

rniucrnns CHASE.

To all whom) it may concern: 7

Be it known that I, STANISLAUS PIWoN- snr, a subject of the Emperor of Austria- Hungary, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and usefullmprovements in Printers"Chases; and I do hereby declare the following to be a full, clear, and exact description of the invention, such-as will enable others skilled in the art to which it appertains to make and use the same, referhad to the accompanying drawthereon, which form a part of this specification.- 1

The present invention relates, generally,

to improvements in printers chases; and,

this invention has reference, more particularly, to a printers chase provided withia novel quoin-operating and retaining means for easily'and quickly fixing the printing type or plates in their fixed relation within the chase ready for use in printing.

The present invention has for its principal object to provide in connection withthe frame of-a chase, a novel means for readily oper'atingtheclamping'or holding quoins of the frame, and a novel means-for retaining the (moms in their fixed relation, afterhav ing been operated oradjusted, so as to securely hold the printing type or plates in their operative relation within the-chase against accidental displacement therefrom, to prevent the quoins from shaking loose, due to excessive vibration and shocks, when printing, and while the chase v platen isplaced upon the printing plate or of the printing machine.

Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

{With the various objects of'the present invention-in"view,the said invention con- 1n the novel printers chase sists', primarily, hereinafter set forth; and, the invention furthermore, in the novel arrangements and combinations of the several devices'and parts, as well as'in the details of theconstruction of the same, all of which will be more fully described'in the following specification, and then finally embodied in 5 the clause'sofYthe claim which are appended Specification of Letters Batent.

to and which form an essential part of the said specification.

The invention is clearly illustrated'in the accompanying drawings, in which Figure l 'is a. plan view of a printers chase provided with a pair. of quoins, all made according to and embodying'the principles of the present-invention, the quo ns being shown in their normal initial positlons, when the chase is not in use. Fig. 2 1s a similar view of the p'rinters chase and the quoins, the latter being represented in ing or holding the printing type or plates in posltlon 1n the frame of the chase, the said type or plates, however, being omitted from said view; and Fig. 3 1s a detail transverse one of their adjusted relations, when clampvertical section, taken on line 8-8 in' said Fig. 2, looking in the direction of the arrower. j S1m1lar characters of reference are employed .in all of the above described views,

to indicate corresponding parts.

- Referrlng now to the several figures of the drawings, the reference-character 1- indicates the rectangular frame of a printers chase,

the same being provided in at leastltwo of its sides, and at the inner marginal edgeportlons thereof, so asto communicate with the inner open partof the frame, with triangularly shaped cut-away portions'o'r depressions 2. Slidably disposed within. each cut-away portion or depression is a wedge shaped quoin, as 3, the quoins being .pro-

vidednear theirlarge end-portions 4: with 'pin-recelv-lng' sockets 5. Extending from the angular, edge-portion; 6 of each cut-away portion or depression 2, and approximately at right angles to the outer marginal edge portions? of the chase-frame 1' are suitably formed pin-receiving purposes of which will be presently more grooves or slots '8, the

fully-described. I v V The reference-character 9 indicates a suitable operating lever or handle which is provided at" its end-portion It) with a pair'of downwardly extending pins or lugs 11 v and 12.

In" operating the device, a wedge-shaped quoin is arranged in each cut-away portion or depression 2, in the manner illustrated in the figures ofthe drawings, andthe; type or plates having been arranged in the chaseframe, suitable bars or plates, as 13, are placed in the frame between the said type or plates and the straight surface-portions 14c of the wedge-shaped quoins 3, the latter being in the positions indicated in Fig. l of the drawings. The respective pins or lugs 11 and 18 of the levers or handles 9 are now inserted in the respective pin-receiving sockets 5 0f the quoins and the pin-receiving grooves or slots 8 of the chase-frame, and by the proper manipulation of the said levers or handles, the wedge-shaped quoins are moved from their normal initial positions represented in Fig. 1 of the drawings to the positions indicated in Fig. 2, as will be clearly evident, and whereby the bars or plates 13 are moved in inward directions against the printing type or plates set up: in the chase frame, so that the said printing type or plate will be properly clamped or looked in place, against accidental displacement and ready for use. As shown in said Figs. 1 and 2 of the drawings, the said triangularly shaped cut-away portions or depressions in the respective longitudinally extending sidemembers and the laterally extending endmembers of the chase-frame, and the corresponding quoins located in said cut-away portions or depressions extend in opposite directions, so that the quoins, when operated,

are moved in opposite directions, to thereby provide more positively clamped relation of the printing type or plates within the chase.

It will also be seen that the respective longitudinally extending side-members and the laterally extending end-members of the chase-frames, at the points Where said members are provided with the quo-in-receiving depressions, are cut-away 0r recessed to provide channels, as' at 15, the quoins being provided with correspondingly formed riblike members or tongues, as at 16, which register with and are slidably disposed in the said cut-away or recessed parts 15. The purpose of these registering parts is to positively retain thequoins in place, after adjustment has been made, to prevent the shaking loose of the quoins, due to excessive vibrations or shocks when the printers chase, with the printing type or plates clamped in place, is placed upon the printing table or platen of the printing machine, as will be clearly evident.

Of course, I am aware that some changes may be made in the general arrangements and combinations of the devices and parts, as well as in the details of the construction of the same, without departing from the scope of the present invention as set forth in the foregoing specification, and as defined in the clauses of the claim which are appended thereto. Hence, I do not limit my present invention to the exact arrangements and combinations of the various devices and parts, as described in the said specification,

nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.
